like parts in the several figures.

This invention relates to machines for inserting nails, and more particularly to machines for attaching heels to boots or shoes.

In the manufacture of boots and shoes it is at times desired to insert in heelsa group or gang of nails which are considerably shorter than those more commonly employed for attaching a heel to a boot or shoe. For instance, heels that are attached to slippers and to footwear of that class are generally of considerably less height than thoseemployed on other classes of boots or shoes, and nails for attaching such heels are required to be correspondingly less in length.

This invention is concerned more particularly with means for facilitating handling of .short nails in a machine for inserting nails in heels.

There is illustrated herein one embodiment of the invention applied to a wellknown form of heel-attaching machine. This for. achine includes a die block pronail passages in which a group of e arranged to move, a foot plate proyi, e with nail passages, means for automatically supplying nails to said foot plate, and a nail transferrer movable between the foot plate and die block and adaptedto receive nails from the foot plate anddeliver them to the die block. In the'use of machines of this class heretofore the employment of short nails has been impracticable for the reason that the shortness of such nails has seriously interfered with their accurate discharge from the transferrer into the die block.

According to the present embodiment of the invention means is provided for supporting a nail transferrer adapted to permit movement of the transferrer laterally of the die block and also vertical movement of the transfierrer with relation to the die block.

There\is also provided mechanism for controlling the path of the transferrer constructed to move the transferrer into close relation to ering position. This mechanism,may conveniently comprise a means tending to maintain the transferrer in an elevated position and means arranged in the path of the trans ferrer constructed to deflect the transferrer downwardly at the desired point in its path.

In machines of the type illustrated a heel carrier and top lift carrier are pivotally mounted to move over the surface of the die block, the heel carrier when the. parts are position to permit nails to be delivered from transferrerto die block having a central open portion above the nail passages of the die block. The application of the invention to a machine of t-hs type permits the transferrer to be moved laterally over the carriers on the die block to a position approximately above the central open portion of the heel carrier and then depressed to bring its lower portion within the heel carrier and its lower face in close relation to the top of the die block.

It will be understood that the invention may be advantageously applied to machines of a form other than that shown for example, to'a heel-attaching machine in which the uppenface of the die block is free and unobstructed by heel carrier or top-lift carrier.

Other features of the invention will be hereinafter described and pointed out in the claims.

In the drawings :-Figure 1 is a view in perspective of a portion of a heel-attaching machine with one embodiment of the invention applied thereto; Fig. 2 is a view in front elevation of a portion of the machine shown in Fig. 1, showing successive positions of the parts; and Fig. 3 is a vertical sectional view.

of the die block and adjacent parts.

In the drawings one embodimentof theinvention is shown applied to a heelenailing macl'iine of a type shown in Letters Patent of the Unite .l;; States No. 694,656, March 4,

1902, to B. F. h layo. I,

In the machine shown a head -1 and die block 2 are provi .led, the die block having nail passages 4, in which drivers 6, are arrangedto move. Suppmted from a frame 8 of the-,1nachine is a post. 10 to which is secureda'n arm 1.2, having atnbul-ar boss to re The boss. may be split ceive -a standard 14. and clamped upon the standard 14 by a bolt 16 to permit adjustment of the standard.

lar boss 24, bearing upon the post 10 to permit pivotal movement of said transferrer tain the deflector 58 normally in the position I about said post 10 from beneath the foot plate 20 to a-point over the die block 2. The transferrer shown is the same in many of its features as that shown in an application for United States Letters Patent filed January 10, 1902, by B. F. Mayo, Serial No. 89,139. It comprises an arm 26 adapted to support a nail receiver 28, represented as a circular plate having a rim 30 to rest upon said arm 26, said receiver having nail holes arranged in the proper order for the particular driving desired. A nail guide 34 provided with a series of holes in alinement with the holes in the nail receiver is provided and as shown is sustained from the under side of the receiver by means of stands 36. The nail guide 34 is located sufficiently below the lower end of the nail receiver and the arm 26. to afford space for-"a nail sustainer and is provided with a centrally arranged extension 37.

The arm. 26 is provided with a stud 38 upon which the nail sustainer 39 is pivotally' mounted, said nail sustainer keeping the nails in the holes of the nail receiver while the transferrer is being moved from nail receiving into nail delivering position. The nail sustainer 39 has projecting from one side of it a lip 41 and near the lip the sustainer has a hole 40, which is entered by a pin 42 in the. transferrer arm 26, said pin acting as a catch. to maintain the sustainer in its operative position. A spring 44 is provided bearing atone end upon. the sustainer and at the other end inserted in a hole in a stud 46 supported by the tubular boss 24, said spring, when the sustainer is freed from the pin 42, immediately moving the sustainer from under the receiver.

The arm 26 of the transferrer is free to move vertically upon the post 10. A spring 48 bears upon the lower side of the boss 24, and tends to maintain the transferrer in a raised position with relation to the upper face of the die block. A block 50 is removably secured to the arm 26 by a bolt 52. The block 50 is provided with a vertical abutment 53. A collar 54 isadiustablv secured tc'the post 10 and is provided with an outwardly extending stud 56 in theend ofwhich is inserted a bolt 57 which pivotally supports a deflector 58. A'spring 60'serves to mainshown in full lines in Fig. 2, and the extent of pivotal movement may be limited by a stop 62 upon the pin 56 cooperating with a slot in the face of the deflector 58. The deflector 58 is arranged to engage the block 50 when the transferrer is approximately over the nail passage 4, and depress the transferrer into close relationto the die block as shown in Fig. 3. portion ofthe deflector 58 is provided with a roller 59, arranged. to bear upon the block 50.

.The block 50 has a projection 64, which when the transferrer is moved towards posi- As shown, the acting tion to receive nails meets the inclined face of a pivoted piece 66 at the end of a rod 68 and moves said rod vertically, which moves a suitable device to start into operation nailassorting mechanism, as provided for in said patent, so that said mechanism may immediately discharge into the nail block 18 a series of nails to enter the holes in thereceiver 28.

. A frame comprising a heel carrier-70 and a top-lift carrier 72 is pivotally mounted upon the upper face of the head 1. This frame may be substantially the same as that shown in said patent. It will be understood that in the position of the parts in which nails are to be delivered to the die block an open portion of the heel carrier is located above the passages 4 and the extension 37 is i rranged in said open portion, as shown in As the nail transferrer arrives in its nail delivering position, the holes therein having been placed in alinement with the holes in the die block, the lip 41 on the nail sustainer meets a stop 74 which acts upon the lip to depress the sustainer and release the same from the pin 42 extending downwardly from the lower side of the transferrer arm, permitting the spring 44 to withdraw the sustainer from its effective position. It will be understood that the sustainer is returned to its effective position as it is moved beneath the foot plate 20, by slop arranged in the path of the sustainer, as disclosed in said. patent.

In the operation of the machine shown, as

the nail receiver 28 is moved from foot plate 20 into nail delivering position, its movement will be horizontal until it is approximately at the end of its path. At this point the deflector 58 engages the abutment 53 on the block 50, and in the further slight lateral movement permitted the receiver 28, said deflector depresses the arm 26 and brings the lower face of said receiver 28 into close relation to the upper face of the die block. In the reverse movement of the parts a slight movement of the arm 26 causes the deflector 58 to release said arm and permits the spring claim as new and desire to secure by Letters Patent of the United States is:
